Answer:  D. (7, 0)

Step-by-step explanation:

[tex]4x+9y=28\\-4x-y=-28[/tex] The xs can already cancel since 4x is positive for the first equation, but negative on the second.Add the equations together8y=0Divide both sides by 8 y=0Plug y into one of the equations4x + 9(0)=28Distribute 04x=28Divide both sides by 4x= 7

So your answer is (7, 0)

Find the approximate Perimeter of a regular hexagon that has an area of 36 mi2 and an apothem of 3.2 mi.
Area = 36 mi2

Answers

Answer:

Parameter of given regular hexagon = 22.32 mi (Approx.)

Step-by-step explanation:

Given:

Area of given regular hexagon = 36 mi²

Find:

Parameter of given regular hexagon

Computation:

Area of regular hexagon = [(3√3)/2]a²

[(3√3)/2]a² = 36

a² = [36 x 2] / 3√3

a² = [12 x 2] / √3

a² = 24 / √3

a² = 8√3

a² = 8 x 1.732

a² = 13.856

Side a = 3.72 mi (Approx.)

Parameter of given regular hexagon = 6 x Side

Parameter of given regular hexagon = 6 x 3.72

Parameter of given regular hexagon = 22.32 mi (Approx.)

Dalgliesh the detective fancies himself a shrewd judge of human nature. In careful tests it has been discovered that he is right 80 percent of the time when he says that a ran­domly chosen suspect is lying. Dalgliesh says that Jones is lying. The polygraph expert, who is right 100 percent of the time, says that 40 percent of the subjects interviewed by Dalgliesh are telling the truth. What is the probability that Jones is lying?

Answers

Answer:

The probability that Jones is lying is 6/7

Step-by-step explanation:

First we will list out 2 different cases when the outcome is a lie

1.probability that Jones tells lies is = 0.6 and probability that dalgiliesh analyses it correctly is 0.8

So the probability that dagliesh correctly analyses that he is telling lies is 0.8*0.6=0.48

2.Probability that Jones tells truth is 0.4 and if dagliesh analyses it incorrectly (which has a probability of 0.2) the outcome(as analysed by dagiliesh) is a lie

So probability that dagliesh analyses Jones truth as a lie is 0.2*.0.4=0.08

Total probability of outcome being a lie is 0.48+0.08=0.56

But we need the probability of Jones actually saying a lie which is nothing but 0.48/0.56= 6/7

Find the surface area of the right prism :​

Answers

Answer:

336 in²

Step-by-step explanation:

Surface area of triangular prism = bh + (s1 + s2 + s3)H

Where,

b = 6 in

h = 8 in

s1 = 10 in

s2 = 6 in

s3 = 8 in

H = 12 in

Surface area of triangular prism = 6*8 + (10 + 6 + 8)12

= 48 + (24)12

= 336 in²

Write the equation of a circle that has a center of (-2, 1)
and a radius 3.

Answers

Answer:

Step-by-step explanation:

(x + 2)^2 + (y -1 )^2 = 3^2

(x + 2)^2 + (y -1)^2 = 9

I have used Desmos to draw this for you. Notice that the center is not (2, -1) but is at -2,1 just as the question requested. The signs are always reversed when the center of a circle must be obtained by squaring the numbers in parenthesis.

Further two points are shown. The one you should pay attention to is (-2,4) which is 3 units away from the center. The other point is also 3 units away, but you have to use the distance formula which you may not be familiar with. If you measure it with a ruler, you will find it is the same distance away from the center as (-2,4) is Since they are equal, they both must represent the length of the radius.

At the candy store, Sophie filled a bag with 2 2/3 kilograms of candy. 1/4 of the weight of the candy was from chocolate covered pretzels. How much did the chocolate covered pretzels in Sophie's bag weigh? ​

Answers

Answer:

The chocolate covered pretzels in Sophie's bag weighed [tex]\frac{2}{3} = 0.6667[/tex] kilograms.

Step-by-step explanation:

Sophie filled a bag with 2 2/3 kilograms of candy.

This means that the total weight is of:

[tex]2\frac{2}{3} = 2 + \frac{2}{3} = \frac{6}{3} + \frac{2}{3} = \frac{8}{3}[/tex]

The total weight is of 8/3 kilograms.

1/4 of the weight of the candy was from chocolate covered pretzels. How much did the chocolate covered pretzels in Sophie's bag weigh?

1/4 of 8/3. So

[tex]\frac{1}{4} \times \frac{8}{3} = \frac{1*8}{4*3} = \frac{2}{3} = 0.6667[/tex]

The chocolate covered pretzels in Sophie's bag weighed [tex]\frac{2}{3} = 0.6667[/tex] kilograms.

A line passes through the point (12,–4) and is perpendicular to the line with the equation y = 6x + 3. What's the equation of the line?

Answers

I'm just gonna so you how I got it

Step-by-step explanation:

6x - 3y - 5 = 0 has slope 6/3 = 2. A perpendicular line will have slope -1/2 (since slopes of two perpendicular lines must have a product of -1), so its general form will be 3x + 6y - a = 0.

Now to find a. We know a point on the line, (4,10), and so we plug those coordinates in:

3*4 + 6*10 - a = 0

12 + 60 - a = 0

72 = a

3x + 6y - 72 = 0.

We can simplify this by dividing all numbers by 3, getting:

x + 2y - 24 = 0

Answer:

x = 12, x = -4.

Step-by-step explanation:

x² - 8x - 48 = 0.

This factors to (x - 12)(x + 4) = 0.

Proof:

(x - 12)(x + 4) = 0

first: x * x

outer: 4 * x

inner: -12 * x

last: -48.

first: x²

outer: 4x

inner: -12x

last: -48

x² + 4x - 12x - 48

x² - 8x - 48.

To find the zeros, take the individual pairs and find the values that make the equation 0.

x - 12 = 0

Add 12 to both sides.

x = 12.

x + 4 = 0

Subtract 4 from both sides.

x = -4.

Emilio "Millito" Navarro never got to play in the major leagues. Still, he was considered to be one of baseball's greats. Navarro, who began his career playing for the Negro Leagues, died on April 30, 2011, in his Caribbean homeland of Puerto Rico. He was 105. In his old age, Navarro was believed to be the oldest living professional baseball player."It is a tremendous loss, but they were 105 years of greatness," said Eric Navarro Rivera, one of Navarro's grandsons, adding, "He gave his all to everybody."Navarro was born on September 26, 1905, in Patillas, Puerto Rico. He became a baseball player at age 17. Before that, Navarro was known as a local champion in three track events.Despite his athletic abilities, Navarro did not have the same opportunities as white baseball players. As a minority, he was not permitted to join the major leagues. Instead, he was given a chance to play in the Negro Leagues, which were founded in 1920 to provide a platform for African-American baseball players. Many baseball teams had hired black players during the 19th century, but by 1900 or so, racism brought about a change in policy. Baseball was racially segregated until 1947, when Jackie Robinson, who was African American, was recruited to the major leagues. Navarro, a 5-foot, 5-inch (165-centimeter) infielder known for his base-running skills, became the first Puerto Rican to play in the Negro Leagues.Navarro was a shortstop and leadoff hitter for the New York-based Cuban Stars of the Eastern Colored League in 1928. He achieved a batting average of .337 the following year. Despite his accomplishments, Navarro recalled experiencing racial discrimination."Back then, there was a lot of racism...," Navarro said. "We [minority] players suffered a lot during that time because we even had to go to different restaurants [than white people]."Navarro left the Negro Leagues after only a couple of years. He played in the Dominican Republic with the Escogido Lions and in Venezuela with the Magallanes and other teams. In Puerto Rico, he was the second baseman for the Ponce Lions for nearly two decades. After retiring from professional baseball, Navarro worked as a coach and an athletic teacher at schools in the Puerto Rican towns of Ponce and Caguas. He also raised a family."He was an... excellent father," said Eric Navarro Torres, one of his sons. "He instilled us with honesty and above all respect for everybody."Navarro appeared on a major league ball field only oncein 2008, at the age of 103. He threw out a first pitch before a game at Yankee Stadium. He warmed up his arm, waved his hat, and made a 30-foot (9.1-meter) toss to catcher Jorge Posada. Asked how the sport had changed since he played, Navarro's eyes widened and he mentioned the high salaries that today's players enjoy."I made $25 a week," he said through a translator.The Associated Press contributed to this story.hint:This question asks about when events happened.
